Replying to need computer for NEW SOFTPLAN 2024... what actually works?

Sure, I've read their minimum computer/setup requirements.... but what exactly works for SoftPlan 2024?  SP says to "future-proof it as best I can to avoid having to make upgrades to it in the near future."  I suppose that's sound advice, but I need to keep costs as low as possible, and all the computer lingo is foreign to me. So... what really works? What setups are people using (without cliches)?
